NAME-PLATE ATTACHMENT.

Specification of Letters Patent.

Patented Feb. "7, 1922.

Application filed October 19, 1921. Serial No. 508,677.

T 0 all whom it may concern:

Be it, known that I, 01.0? NELSON, a citizen of the United States, residing at .Xttieboro, in the county of Bristol and State of Massivchusetts, have invented certain new and useful Improvements. in Name-Plate Attachments, of which the following is a specification.

My invention is an improved means for connecting a name or emblem plate or the like to any desired supporting surface. The immediate and particular object I have in view is to secure a name or emblem plate upon the shell or cover of the. radiator of an automobile. This radiator shell is in cfl'ect a cover for the radiator proper. which is a cellular or tubular element, through which the heated water from the water jackets of the motor cylinders is passed to dissipate heat units to the air, and the shell fits the radiator closely, so that it is difficult or impossible to insert hands or tools between the shell and the radiator or to get, at the inner surfaces of the shell without removing the shell from the radiator.

In the drawings:

Figure 1 is a front or plan View of a por tion of a radiator cover or other supporting surface, slotted to receive a name or emblem plate;

Figure 2 is a section on line 52-2 of Figure 1;

Figure 3 is a rear view of an emblem plate, carrying the connecting device secured thereto;

Figure 4 is a central section of an emblem plate attached to a. radiator cover;

Figure is a perspective View of the attaching device separate from the name plate; and

Fignr 6 is a cross-sectional view on line 66 of ignre 5.

My connector is made in two parts and the engagement between the two parts is a friction locking engagement. The engagement and locking is accomplished by the interaction of the parts themselves. when they are brought together. The result is that the ctr gagemcnt is effected with the utmost simplicity and security so that the vibration of the machine. in use has no cttcr't whatever upon the union of the parts which retain their engagement. until force is designedly applied between the parts to separate them.

One element of my connecting device is shown in Figures 5 and 6. It consists preferably of a metal tube, (1 having a flattened side a and split at a along the side opposite to the flattened side. This tube is secured along its flattened side by soldering, brazing or other means, to the back of the name or emblem plate A.

In another plate or preferably in the substance of the front of the metal radiator shell B, at the desired point of attachment, I punch a slot, 5, of a length very slightly greater than the length of the tube, a, and having in-turned lips, 72 (see Figures 1 and 2). The free ends of the lips b slant-toward each other and are set and spaced apart a designed distance in the punching operation. The distan e designed will have relation to the cross-sectional size of the tube, a, with which, as will be presently explained. the lips b cooperate in use. It will he observed (see Fig. 6) that the edges a of the split tube are separated.

In applying the name or emblem plate to the supporting surface, for example, a, motor car radiator shell, the tube, a, secured to the emblem plate (see Fig. 3) is inserted in the slot, b, and is pressed into the slot. The metallic tube, being wider than the distance between the free edge of the lips, I), wedges the lips I) apart and is itself, by the resist ance of the lips to this wedging section, distorted, the edges a, of the split in the tube being forced to approach each other as the edges of the lips pass onto the widest part of the sides of the tube, when the inherent resilience of the two connector parts causes the opposed surfaces to be engaged with a powerful resilient friction grip.

This operation is most easily performed, for the wedging action multiplies the force applied in sition and reacts to 'the force e'm lo'yed, (which .is per atlicnlar to the surgzce of the radiator shell} substantially in a direction parallel to the surface of the radidtor shell, which is not therefore pressed inward in any damaging manner.

The attached name plate is held tightly and securely, without rattle or possibility of working loose. and cannot rotate nor change its position longitudinally or laterally, un-' less force is applied desigucdly to break the frictional grip of the connector elements, while the force required to establish the frictional grip, owing to the shape and organization of the parts is in a direction having no tendency to dent or damage the radiator shel1.,-

I have'described above the preferred embodiment. of my invention in which both elements'of'the attacln'n device have free edges or lips, capable of %eing forced apartor together, An "engagement may be effected however where only one of the parts has freeledges or lips, and such a device, while not so efiective; would be within my invention;

I claim:

1. The attachin device above described, consisting of a tu ular wedgeneinber and a plate having opposed free lips on either side of :1. slot therein. to receive the wedgemember between the lips.

2. The attaching device above described, consisting of a slotted tubular wedge-mam i081 and a plate slotted to receive the slotted edge-member. l

3. The attaching device above described, consisting of a slotted, tubular wedge-n1emher and a plate having opposed free lips on i either side of a slot therein, to receive the slotted wedge-member. V

Signed at Attleboro, Massachusetts, this fifteenth day of October, 1921.
